Take the Poison Joke

Man goes to see the Rabbi. "Rabbi, something terrible is
happening and I have to talk to you about it."
The Rabbi asked, "What's wrong?"
The man replied, "My wife is poisoning me."
The Rabbi, very surprised by this, asks, "How can that be?"
The man then pleads, "I'm telling you, I'm certain she's
poisoning me, what should I do?"
The Rabbi then offers, "Tell you what. Let me talk to her,
I'll see what I can find out and I'll let you know."

A week later the Rabbi calls the man and says, "Well, I spoke
to your wife. I spoke to her on the phone for three hours. You
want my advice?"
The man anxiously says, "Yes."
"Take the poison," says the Rabbi
